advice needed on shell script 1

[Tels]

Thanks in advance for your help..
I have two RH7.1 webservers running Samba and Apache.
I want to keep both servers web content synchronised by running a script.

I intend to use samba to make the /var/

http://www/html

directory available, and have a script to a) mount the remote share, b) copy (and overwrite) the existing files and folders from the remote /var/

http://www/html

share to the local one

I do not know how to mount an smb share in *nix (normally we use win2k clients) and no experience in writing shell scripts - although I have some in java/perl

The main issue I need advice on is how to copy all the files and folders recursively (I have a notion it involves looping) - has anybody got any advice to get me started?

I really would appreciate help, I'm a fairly new to Linux, but I'm hopelessly hooked.

Regards

Samba is only used to share information between Windows and *nix computers. If you want to share information between 2 *nix computers, you need to use something like NFS. Another option is to use something called rdist. rdist is a utility that allows you to maintain identical copies of files over multiple hosts. Typically, content is developed and placed on a single master server and then is distributed to all the other web servers.

If you want to use NFS, you can set the 'shares' up in the /etc/exports file. Here's an example share in /etc/exports....

/home/chris some.host.com(rw)

Here's how you would mount the above share from the other Linux computer...

mount –t nfs linux01:/home/chris /mnt/nfs

linux01 is the NFS Servers hostname. Make sure to restart the NFS server whenever you make changes to the /etc/exports file...

/sbin/service nfs restart

If you want to always mount this share when your server boots, add it to the /etc/fstab file...

linux01:/home/chris /mnt/nfs nfs hard,intr 0 0

I forgot to answer the question on the script. If you want to copy all of the data from the NFS share to /var/

http://www/html,

write a simple script like this...

cp -fR /mnt/nfs/* /var/

http://www/html/

You can execute this script periodically using cron.

Top answer! sounds like exactly what I need. I'll wait until the machine has finished compiling and test it out.
